Time Lapse video of the sun's shadow on August 21, 2012. I've been wanting to do this for years but never had the proper equipment. This is my first attempt and I'm really happy with how it came out.
Filmed using the Timelapse Camera HD app, taking a picture every 15 seconds with 20 frames per second playback.

GazdonianProductions so how ya wrapping ur head around today's sun, location and ancient sundials and monuments that use the sun like stonehenge?
Would you mind informing at what city was this video made in? I'm making a simulation about sundials on different places around the world
Albany NY
thx now i can stay inside to do an outside experiment
one of the greatest sciences I've ever seen, better shadow video is better than school.
Congratulations
this is one of the most usefull things i've ever seen
Mimi Salajan agreed, i literally watched it in school and now I’m home watching it again because I’m bored lol
This is one of my biggest obsessions and fixations around like cardinal directions and time stuff!!
This is how people got to know about what time is it in olden days. By looking at the shadows.
They specifically used tools to tell them with shadows. Those are called sundials
They have buildings that were built on the frequencies above and below, like halos for example. There are windows designed for the end times, like a chronograph that will tell when the days get shorter and the sun will go black like clockwork, so the elite will go to their underground City's with the help of the sun simulators 🌞
Wow the shadows are awesome. Thanks for the upload.
That's a really cool effect.
Thanks
Best experiment of Shadow ever 🏆
that is fantastic for learning about shadows!
thanks for helping me on my last minute project dude!
The sun's shadow traces a near-perfect straight line because the shadow traces out a line of latitude. Lines of latitude are essentially indistinguishable from great circles on the local scale of someone standing on the surface of Earth.
Wonderful video! I cant wait to show my class.
Thank you, full day lapse night-day would be usefull too
Any one have clip showing shadow from 7AM to 4 PM?
So you must be east of your time zone meridian by about 35' longitude since transit is around 11:25 am. Knowing the date, the right ascension and the declination of the sun can be estimated. An estimate of the height of the block and its shadow can give the elevation of the sun at transit. From the data collected at this point, the latitude can be estimated.
All it would take at this point is observation of the environment to pinpoint the exact area this video. I'm guessing somewhere in the eastern part of new york state or in new england assuming the environment and that this video is in english. The grass looks like the grass where i live, which is in the northeast us.
You recognize the grass????
@@MisterGazda If it's native you could. But this looks like a manicured grass patch. You'd have to be well versed to make out the brand/type.
Very useful, thank you
The north arrow represents 12 o clock And the taller the shadow it gets later
Oh my 😲 wow!!
Enchanting!
Very Important and interesting
Its very much important
It recorded from 10:39 to 17:22 (6 hours and 43 minutes)
Which location you recorded this video?
Albany, NY USA. Latitude 42 degrees North.
That's why tall building architecture size shape and texture determine what kind is psychology citizen in the city had and it called soul of the city mean the shadows , noise , and sunlight create entire human genome and RDN and DNA
thanks man
My class and I would like to know what part of the country you are located it in? Thank you for sharing the video! Our school property is covered in snow and ice right now and doesn't make it easy for us to do this on our own.
Jessica Dauscher This video was filmed in Albany, NY which is also covered in ice and snow right now...
MisterGazda YES! You most certainly are! Thanks again for sharing and greetings from Iowa!
Nice, adding the clock was a good choice ,would have preferred some music to this though ,thumbs up m8!
is this really made on August 21, 2012? in the video it looks like midday is at 11:38 (0:11min Midday when Sun is in Zenith = South = Shadow North) and if i look on the timetables for Albany, NY on August in 2012 there is a huge difference. Maybe I misunderstand smt. ?
This is because the North arrow I drew on the driveway is off a bit. It was difficult to transfer due North from my compass to the driveway and that lead to the discrepancy you noticed. But it was definitely Aug 21, 2012 in Albany NY.
@@MisterGazda ok, thank you, now it makes sense.. still a great video!
If sun rays are practically parallel why does the shadow appear larger towards the top of the board? (the "tip" of the shadow appears to to be wider than the "base")
This doesn't appear to happen in your other video czcams.com/video/K0oLY5z5kQA/video.html
Am I just imagining it, or being tricked by the camera's perspective (being closer to camera) making it seem larger at the tip? If you were to measure the width of the shadow along its length we should expect it to always have the same width, yes? Provided the sun is the only light source.
Yeah, I don't know. When I look at the thickness of the shadow it can look either wider at the tip or not. It could be that the driveway it a bit uneven (which it is) but I don't think that's causing it.
That's just perspective. Look at a perfectly cut plank of wood in front of you and it will appear larger (i.e., have a larger angular size) in width the closer the point on the board you look at with your eyes is to you. This applies to all rectangles on the ground, not just shadows.
Looks like you are north from the equator inside the arctic (arcus) of the sunpath. In the South of the sunpath you are ouside of the Arcus in the Antarctic region and the shadow moves anti-clockwise.
This is excellent and perfect for my NY Earth Science Regents class (maybe you teach this too as you are from Albany?) Thanks for a great job and for sharing it with us.
+Andrew Orgonik I do teach NYS Earth Science and that's the main focus of this youtube channel. Glad you dig this video. Thanks.
If the earth spins a 1000miles per hour then why is it taking this shadows an entire hour to move a measly few inches?
Because of the distance. We are from the SUN
Spins are measured with rotations per time and shadow movement per angle change. Since earth rotates just once every 24 hrs, shadow will change angle by 15° per hour (360/24 = 15). And this is exactly what you see here.
That tree shadow came outta nowhere
It's a ninja tree.
whos here because of school
where ? time of the year ? camera white balance ?
noice!
This gives me a new perspective when reading James 1:17 “there’s no Shadow of Turning in God”
anyone good at celestial navigation thinks you could find the coordinates
The Sun just moves away...
Timelapse not long enough, what happens when the sun goes over the horizon???
Hi, can I use your video for my student art project?
Please go to my website GazdonianProductions.com and email me directly.
Is the floor level
Hi, I've used your excellent video as a basis for a comparison experiement between expected results on a globe vs flat earth. The results are interestng! (but not entirely surprising!) As a courtesy, I'm just asking your permission before I use it, I'll give full credit of course. Thanks
Yes you can use my video but please give me credit as well as link to my video in the description.
GazdonianProductions yes of course, no problem. I’ll send you a link when it’s up.
GazdonianProductions a quick question if I may, you mentioned in a comment that you used a compass to align to north, shall I assume the your north market points to magnetic, not true north? It’s part of my analysis so would be good to know for sure. Thanks
Yes, I used a compass so the North arrow represents magnetic North.
GazdonianProductions great, thanks
Had to use this to learn something at school 😂
If you want the real north line just go to 0:16.

Even your Noon has a shadow. You must be in the Norther hemisphere. I live pretty close to the equator. No noon shadow for us here.
Good point! This video was filmed in Albany NY (latitude 42 degrees N latitude), so you are correct in that it was filmed in Northern hemisphere.
note: theoretically, you should experience a small shadow at noon every day of the years (except 2 days). But on a practical level it would probably be very difficult to notice most of the time because it would be rather short.
why is the shadow didn't dissapear during the noon
This was most likely filmed in NY. The Sun does not reach the zenith (directly above the observer) at this latitude. This only occurs between 23.5 N and 23.5 S. At solar noon the shadow will be shortest because the Sun is at the highest angle but because it is not directly overhead it will not "disappear".
ما شاء الله
Firestyle fireball justu
thanks!
0:12 *Pauses* Well, seems like this is when the clocks time makes a shadow point n___h
I dont get what im seeing🤷🏻♂️
Who's also hear from doing a project
se fosse no brasil já teriam roubado esse relógio
I believe Daylight Savings Time plays a role on this too. If Clocks were never invented we wouldn't have daylight savings time either.
Daylight savings times has nothing to do with the sun's apparent motion across the sky and the shadow it casts.
Note: Since this time lapse was filmed during daylight savings time, I changed the clock in the video back 1 hour so solar noon and noon on the clock coincided.
how else is waching this in bsk british school of kuwait
So the earth is not flat? Thank you, the sun runs straight from east to west instead of circling the north. :)
I don't know what you are talking about. On an unofficial flat Earth map, the sun is circling the USA from east to west and circling the north. The sundials prove the same thing.
I saw the shadow move EXACTLY as it would on a flat earth with the sun circling above. If it was a Ball spinning the the shadow would not have spun around like that but only moved in a linear fashion. from right to left with very little circular movement.
mojo jojo you got a shoutout on my video! Not sure you’ll like it though... czcams.com/video/2bnzyO6CC2o/video.html
@@christ4u2now There is no "flat Earth map".
At sunrise or sunset on a ball your shadows would not go DOWN..... czcams.com/video/Hyipj4CjIH0/video.html
who played this on 2x?
Me
Im actually Arabian, not english
انا اسمي ريتال❤️❤️ ❤️❤️
Uhh not helping
My teacher sent me this video
My teacher play this video in class she name is Ms.corkins
Midday at 11:25 am
It was difficult to get the North arrow accurate when I was setting this up, as I had to eye it up from my compass. So that lead to the N arrow being off a little, thus making it appear that solar noon is at 11:25 (actually maybe more like 11:35) when it should be 12 noon. That's the main flaw with this time lapse and it bothers the heck out of me.
11:25 is when the shadow is exactly parallel with the line of the arrow, that's why I said 11:25, I see that 11:35 is when the shadow appears to be pointing at the arrow line but it is not parallel with the arrow direction. I get what you're saying about not getting the arrow exact but in reality solar noon is rarely at 12 pm exactly as the time within each time zone is based on fixed time zone lines, if it wasn't you would have to change your clock backwards if you move west and forwards if you move east relative to how far you travel in either direction. lol
Good point about the shadow being parallel, so based on that I agree that 12:25 is the good time for when this video shows solar noon to be. Also a good point about the time zones and how solar noon at any location is usually not exactly at noon. Though at Albany NY where this was filmed solar noon in July is usually just a couple of minutes off from 12 noon (note: I actually changed the clock in this video back 1 hour to account for the fact that we were in daylight savings time when this was filmed, so solar noon occurs at 1:00 on the clock that time of the year.) Thanks for the comments.
Ah nice, good video BTW. :)
The North arrow should represent 12 pm but it is 11:37 23 minutes off.
For CHEESSEE
Can I watch paint dry
don't judge me
shadow looks like the sun was circling overhead and getting further and further away in the evening...hmmm interesting huh ball earthers?
Are you sure about that, flat earther? Did you just assume from eye BALLing it or did you plot the movement of the shadow when you made that conclusion?
I plotted the sun shadows and it gives the opposite result that you get from a flat-earth model. czcams.com/video/ti9c8G7Kwio/video.html
I don't understand. Why is the sun setting in the East?
Maybe the location is in australia
The shadow at the end of the video points east which means the sun is in the west.
gta v be like:
And Eratosthenes said that shadows were parallel??? Lol 😂
Shadows cast by the sun are parallel. Eratosthenes was the man!
yes and they are
This has got to be fundamentally the most retarded comment
At what latitude?
tks
42 degrees 39 minutes North
my teacher told me to watch ur video !!!!
In Quraan God talk about this
shadows are not-moving !!!
If you conducted this experiment 10 years prior, you would realize how much of our sky has changed circa 2010. The sun and moon have changed their patterns. The rules have changed because civilization on Earth have gotten worse. Civilization continues to break down in 2022 and the future on Earth looks very grim. Civilization badly needs to make good or we're going to the point of no return.
This proves the earth is flat and fixed with the sun moving above it tracking the sun's positions in the sky.
Ah, no, it's really not. That idea of the flat earth is so wrong in so many ways, when examining the sun's position in the sky.
my teacher told me to watch this and i disliked it hahahahhahahhahahah im despicable
This is boring
That's 1 min and 21 seconds of your life you're never gonna get back.
